To all w/wm/ it 1%ar cn0ern:

Be it known that I, WILLIAM H. Voss, a

citizen of the United States, and a resident of Davenport, in the countyof Scott and State of Iowa, have invented certain new'and usefulImprovements in Dashers or Stirrer- Heads for Washing-Machines, of whichthe following is a full, clear, and exact description.

My invention relates to the dashers o'r stirrer-heads ofwashing-machines; and its object is to make a light, durable, 0 en metaldasher through which the water an suds can easlly percolate, which willnot swell or be affected by the swelling of the stirrer-pins or dowelswhen kept wet for any considerable length of time, and to which saiddowels can be readily and securely fastened in proper position,regardless of defects in their manu-. facture, without alteration orremoved as desired. This I accomplishby the means hereinafter fullydescribed and as particularly pointed out in the claims.

In the drawings, Figure 1 isa vertical central view of the centralpprtion of the top or cover of a washing-mac no and the stirrershaftthereof, to which latter my improvements are applied. Fig. 2 is a planview of my improved dasher. Fig. 3 is a side elevation thereof.

Reference being had to the drawings, A

' represents the top or cover of the tub of a washing-machine, and B thesquare stirrershaft thereof, journaled in suitable bearin s a in saidcover and in an overhead frame substantially as shown. Shaft B has avertical movement independent of its rotation, and its upper end above.frame I) is provided with a suitable nut or headc to limit its downwardmovement.

My improved metallic dasher or stirrerhead is secured to the lower endof said stirrer-shaft B and comprises a central boss 0, which has asquare opening or socket extending centrally down into it for thereception of the end of the shaft B, to which latter it is secured by atransverse pin or rivet cl. The

I lower closed end of this boss has a concentric disk 6, which has asuitable number of perforations e therein, and has its upper edges fflanged upward. Projecting radially from said edges f are fourequidistant corresponding arms, each consisting of parallel side members9, of the same height as the flanged edges f, the outer ends of whichare preferably increased in height and connected by a verticallydisposed transverse web h, the outer surfaces of which are concaved toform seats for the shanks F of the wooden dowelor pin G, secured totheouter end of each of said arms. the members 9 are provided withvertical slots 7', that extend down from the upper edges thereof asuitable distance, and when the pins are to be secured in place a bolt Dis passed diametrically through a'suitable opening in" their shanks,each. of which has -a nut E on its inner end. The threaded barrels ofthese bolts are passed into said slits and when said nuts are tightenedsecurely hold the pins G in position. The openings in the shanks ofthepins through which the bolts are passed are located in the same relativeposition in each of said pins, and the slits in the end of each arm areof the same depth, so that when the parts of the stirrer-head areassembled the said pins will all be securely fastened in place andextend below the stirrerhead the same distance.

My improved stirrer-head is referably cast in one piece of metal and enales the water and suds to percolate therethrough without interference,and it is not aflected by the moisture or liable to split when the pinsare driven into it, which latter occupy the same relative position tothe stirrer-head and can These webs h midway between be readilytightened in lace should they become loose or easily rep aced shouldcome broken.

What I claim as new is 1. A stirrer-head for washing-machines comprisinga metal boss, equidistant open arms cast in one piece therewith andprojecting therefrom, wooden pins and transverse bolts and nuts by meansof which said pins are removably secured to the ends of said arms.

2. A stirrer-head for washing-machines comprising a metalboss having anintegral concentric perforate disk the edges of which are flangedupward, equidistant open arms cast in one piece therewith and projectingfrom the upwardly-flanged edges, and wooden pins removably secured tothe ends of said arms. v

8. A stirrer-head for washing-machines comprising avmetal boss having anintegral concentric perforate disk the edges of which are flangedupward, equidistant open arms cast in one piece therewith and projectingfrom the upwardly-flanged edges, and having concave seats in their outerends, and wooden they be pins secured in the seats in the ends of saidarms.

4. A stirrer-head for washing-machines comprising a metal boss having anintegral concentric perforate disk the edges of which are flangedupward, equidistant arms each consisting of parallel side members castin one piece and projecting from said upwardlyflanged edges and havingtheir outer ends connected by a transverse web, the outer surface ofwhich is concaved, and wooden pegs seated and removably secured in theconcave ends of said arms.

5. A stirrer-head for washing-machines comprising a metal boss having anintegral concentric perforate disk the edges of which are flangedupward, equidistant arms each consisting of parallel side members castin one piece and projecting from said upwardlyflanged edges, and havingtheir outer ends 4 connected by transverse webswhich latter have avertical slit therein, and have their outer surfaces concave, woodenpegs, and bolts and nuts for removably securing said pegs in the concaveends of said arms.

6. A stirrer-head for washing-machines comprising a metal boss having anintegral concentric perforate disk the edges of which are flangedupward, equidistant open arms cast in one piece therewith and projectingfrom the upwardly-flanged edges, Wooden pins and transverse bolts andnuts by means of which said pins are removably secured to the ends ofsaid arms.

In testimony whereof I have hereunto set my hand this 6th day ofNovember, 1905.
